Abstract: A molded siding member having an encapsulated foam core that extends substantially the entire length of the member in which it is contained, and a molding system therefor. The siding member includes a cementitious shell molded about the foam core, the shell being formed from cementitious slurry, including gypsum cement and a latex/water mixture, or hydraulic cement. After sufficient curing, the siding member is removed from the mold and is ready for immediate use and/or further processing. Also, production methods are disclosed, including a continuous method for producing relatively long lengths of the siding that can be cut to an appropriate size, without the need to produce individual siding members of limited size.

Abstract: A molded siding member having a plurality of longitudinal support portions extending substantially the entire length of the member contained therein, each support portion presenting a cross-section generally shaped like that of an I-beam. The support portions, which are parallel and adjacent to each other, are integrally formed with the siding member from cementitious slurry, including gypsum cement and a latex/water mixture, or hydraulic cement. An amount of the slurry is added to a mold in which longitudinally-oriented core elements are provided that displace cementitious slurry between and define adjacent support portions. After sufficient curing, the siding member is removed from the mold and is ready for immediate use and/or further processing. Alternatively, a continuous method is also provided for producing relatively long lengths of the siding that can be cut to an appropriate size, without the need to produce individual siding members of limited size.

Abstract: A siding member having longitudinally-oriented reinforcement fibers material extending substantially the entire length of the member contained therein, and an optional meshed reinforcement material contained therein and/or an optional foam insert at least partially enveloped by a cementitious shell. The siding member is molded from cementitious slurry, including gypsum cement and a latex/water mixture, or a hydraulic cement. An amount of the slurry is added onto a bottom mold surface portion to a desired depth and/or weight, along with the longitudinally-oriented reinforcement fibers and the optional meshed reinforcement material and/or any optional foam insert. After sufficient curing, the siding member is removed from the mold and is ready for immediate use and/or further processing. Alternatively, a continuous method is also provided for producing relatively long lengths of the siding that can be cut to an appropriate size, without the need to produce individual siding members of limited size.

Abstract: A board-type or log-shaped cementitious siding system, or a cementitious roof shingle system, having a reinforcement material contained therein, and an optional foam insert at least partially enveloped by a cementitious shell. Each system is molded from cementitious slurry, including gypsum cement and a latex/water mixture. A reinforcement material and an amount of the slurry are introduced into an open molding system or an alternative closed molding system, either molding system including a mold surface member having a face defining an exposed surface of the siding or roof shingle system. The slurry introduced to the mold surface member is to a desired depth and/or weight, or for a desired period of time. A foam insert is optionally introduced into the molding system. After sufficient curing, the siding or roof shingle system is separated from the mold surface member and is ready for immediate use and/or further processing.

Abstract: A stone work simulation system including panels formed from a cementitious material. The panels of the system can be cast or injection molded from cementitious slurry, including hydraulic cement, or gypsum cement and an optional latex/water mixture. A desired amount of the slurry is added to the mold, the surface of which includes several spaced apart depressions formed therein to closely resemble a pattern of stones at least partially disposed in a mortar matrix. Optionally, the mold can include a number of flat spaces formed between the depressions. Optionally, a reinforcing mesh is also provided in the mold. A colorant can be disposed on the bottom mold surface prior to the introduction of the mesh and the slurry to impart a color pattern to the system. After sufficient curing, the panel is removed from the mold and is ready for immediate use and/or further processing, such as additional surface coloring. In use, the system can be mounted to a building surface, such as a wall, e.g.
